ln a pending application for Letters PatrThe conveyer cliute constituting the in ent tiled b y ine in the United States Patent subject of the present application, is formed Ottico on improvements in placer mining from sheet metal. as steel. The device coniiiacliines (Serial Number 616,636) certain sists of oppositely inclined,' longitudinally improvements in conveyer chutes were repextending imperiorate sides a, a, diverging resented, but not claimed in said applicain a downward direction from the upper 7.9 tion. rllie present application relates to imhorizontal central apex al; tli'e lower edges provenients in conveyer chutes and more e of said sides are also beveled or inclined especially to the conveyer chute represented downwardly troni the rear end of the ridge in said application. or apex al and are constructed to form open The object .l have in view is to increase sid-e troughs or what may be termed sub- 2o the etiiciency ot' conveyer chutes oic the relachutes as, each having a substantially U- tively stationary type, whereby the material shape, transversely: the outer vertical side acted upon, such for example7 as clay, walls thereof terminating in a continuous gravel and ore-carrying material in its pastiange lig.

l claim as my invention:

l. A s an improved article of manufacture, a conveyer chut-e et the general character described, consisting of oppositely disposed longitudinail;7 extending sides dive-rging downwardly from a common ridge or apex, an inclined outer trough located atthe lower edge of each of said sides in open communication therewith, inwardly facing lateral troughs into which said side troughs discharge located at the lower end of the conveyer, and a common outlet in open communication with said lateral troughs.

2. The improved conveyer chute substantially as herein described, the same compris-v ing a pair of longitudinally extending downwardly divergent sides united at the top, each of said sides having its lower edge provided with a trough parallel therewith, inwardly facing transverse shorter troughs leading, respectively, from the lower ends of said side troughs, and a discharge outlet intersecting the transverse troughs, constructed and arranged whereby, when mounted and positioned as in use, disintegrated material, as clay &c., continuously collected in the longitudinal troughs, flow downwardly therein and are deflected into said transverse troughs in open communication with the discharge outlet.

3. A n integral conveyer chute consisting of a pair of downwardly divergent impertorate sides connected together at the top, the lower edge of each side being inclined downwardly toward the lower end of the device, side troughs in open communication with the impertorate sides at their lower edges, means terminating in a common discharge outlet communicating with said side troughs arranged to conduct material from the latter by gravity, and means for securing the conveyor chute in a normally stationary position.

ln testimony whereof have atliXed my signature in presence et two witnesses.
